Tom DeLay is sentenced to 3 years. I hope he doesn't wriggle out of it.

I still feel that he was railroaded, under the same terms and conditions concerning campaign contributions submitted for one's party, as the Democrats had also previously done in the past. Am I mistaken in saying that he didn't pocket any money? But he was only interested in acquiring more 'power' for the sake of his party.

Sure....

Many of us in the US have just learned that "trading on insider information" is perfectly legal for US Senators and Congressmen. This has to be changed.

Exactly ... Close these workaround loopholes to corporation contributions ...
Close them with jail terms. At the very least take away, though hard to prove,
any illegally gained assets.

Examples: Some one in the government knows a FDA will pull a drug off the market...sells the Drug Co. short.

Buys farmland and then gets a highway to pass adjacent...sells the farmland for big profit.
Knows Gov. is about to give Co X a big grant...buys Co X stock.
